provide and use BUS_SPACE_BARRIER_xxx.

bus_space_alloc() as a bitmask of flags, and not a boolean controlling
cacheability; and make sure the three MI BUS_SPACE_MAP_xxx values documented
in the manual page are defined on all platforms as well.

the motherboard eisa id, instead of using a ``one size fits all'' value which
is too large on more than half the eisa-capable alpha designs.
The id -> slot # logic is based on the alpha ECU configuration files, so we
should not perform worse than ECU itself (and see all slots ECU sees too).

|
bother trying to probe more.

per-platform implementation, instead of selected members of it; this allows
us to get rid of some globals, and paves the way for better bridge support
on some models.

plugged to the bottom 4 PCI slots of AlphaServer 1000A (attaching to pci1
behind a ppb) to get interrupts.
No regressions on AlphaServer 800 (which do not have these extra slots).

is not used yet, but this seems to ``warm up'' the eisa chips so that
accesses to the eisa bus later do not cause machine checks.

instead of only the starting address. From NetBSD.
|
|
Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

appropriate. Removes unwanted messages that got printed when mapping pins
on PCI-PCI bridges that don't matter.

size(*p) as the first malloc() parameter where p is declared locally
and thus easy to check. Add M_ZERO to gpe_table allocation in acpi.c
even though there is no obvious bzero or memset nearby.

This code makes it possible to run on some of the AlphaServers,
namely AlphaServer 4100 and 1200.
add mcbus(4) and mcpcia(4) to provide support for the system bus and
the MCPCIA-to-PCI bus adapter that can be found in these systems
allow the pci_swiz_bus code to handle variable extent names
to be able to handle more than one mcpcia(4)

domain number such that we can distinguish between busses with the same bus
number that are behind different host bridges. Domains can be accessed by
using different device nodes.

Rather than an "iointr" routine that decomposes a vector into an
IRQ, we maintain a vector table directly, hooking up each "iointr"
routine at the correct vector. This also allows us to hook device
interrupts up to specific vectors.

eventually we can determine whether or not to allocate a spill
page on a per-mapping basis.

NULL for root PCI busses. For busses behind a bridge, it points to
a persistent copy of the bridge's pcitag_t. This can be very useful
for machine-dependent PCI bus enumeration code.

interrupt counter for a given shared interrupt descriptor.
When an interrupt is successfully handled, reset the strays counter,
thus preventing a "slow leak" from eventually shutting off the interrupt
vector.

names.
However, the tsp code uses one global extent, which both device instances
want to reinitialize and use for themselves (whether this is a genuine bug
or not is left to the reader).
Solve the problem by putting the extents into the tsp softc, and change the
pci_bwx_bus code to handle variable extent names.
This makes DS20 systems with tsp0 and tsp1 work again.
